The answer is 36π or approximately 113.1 cm.
Surface area = 4*pi*32 = 36pi square cm
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 10 cm, the surface area is4 (3.1416) (10)2 = 4 (3.1416)(100) = about 1256.64 cm2
Surface area of sphere: 4*pi*15^2 = 900*pi square cm
The sphere's diameter is 3.921 cm
The answer is 36π or approximately 113.1 cm.
The surface area of a sphere with a radius of 7cm is about 615.8cm2
The surface area of a sphere with a radius of 42cm is about 22,167cm2
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Surface area of sphere: 4*pi*7^2 = 196*pi square cm
Surface area = 4*pi*32 = 36pi square cm
Surface area = 4*pi*142 = 784pi square cm
Surface Area = 4*pi*r2 = 6566.9 sq cm
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 10 cm, the surface area is4 (3.1416) (10)2 = 4 (3.1416)(100) = about 1256.64 cm2
Surface area of sphere = 4*pi*122 = 1809.557368 or about 1810 square cm
The surface area is about 314.16 cm2The formula for the surface area of a sphere is 4 (pi) r2For a radius of 5 cm, the surface area is4 (3.1416) (5)2 = 4 (3.1416)(25) = about 314.16 cm2*Do not confuse the sphere's surface area formula SA = 4 (pi) r2 withthe formula for the volume of the sphere, which is V = 4/3 (pi) r3
It is: 4*pi*62 = 144*pi square cm
